Electrostatic Print Head and Method of Manufacture

Electrostatic print head module 10 has wires fanned out laterally to accommodate a multiconductor connector.

Print head 10 comprises a plurality of steel wires 11 mounted in fanned formation between two layers of thin plastic sheets 12, 13 and 14. Module 10 is formed by laying sheet 13 on pressure plate 15 and placing an etched terminal board 16 on the upper surface sheet 13. A plurality of wires 11 is individually placed on the sheet. Wires 11 are held in place at one end by jig 17 mounted on plate 15. They are held in place at the other end by the terminal board 16.

Sheet 12 coated with a pressure sensitive adhesive is pressed upon the assembly, the pressure being applied by a second pressure plate. Upon removal of the second pressure plate, precision mounting clasp 18 is attached to the narrow end of the module. This method is adaptable for forming two modules simultaneously by using a symmetrical arrangement and then cutting the formed module at the midpoint.
